Abstract
Three ticks indigenous to the USA were assessed for their ability to maintain and transmit African swine fever virus (ASFV). Amblyomma americanum and A. cajennense adults and nymphs maintained virus for 4-7 days after engorging on infected swine blood; virus was not carried through the subsequent molt of nymphs and it was not transmitted vertically to the eggs and larvae of the infected females. On refeeding of the ticks, infection was not transmitted to healthy swine. O. coriaceus adult females did not show transovarial transmission of 2 strains of ASFV. Nymphs maintained virus for 77-118 days through a molting stage and transmitted 1 strain of the virus (Lisbon 60) to healthy swine.
